My NCEES still says "Exam results/diagnostics not yet available", however TBPE exam results say I passed. Looks like NCEES will be waiting for something from each state board before they post the results on My NCEES.
I hope so. NCEES and the state boards are probably more excited for the results than we are. I can't imagine what it must be like to answer their phones.
With enough results we could see the highest raw score (43 in the example). Whatever the highest score reported +/- a couple would give a pretty good idea of the size of the curve.
